Android广播问题 - 接收消息60秒延迟

Question

我们有一个使用以下代码广播消息的进程。该消息由BroadcastReceiver接收和处理（如下所示）。我们在一些Android平板电脑和手机上遇到了一个奇怪的问题。接收器不会在60秒内接收到广播的消息。好像有些东西会阻止消息被广播/传送60秒。我们对代码进行了三次检查，代码中没有引入任何人工延迟。还有其他人看过这个问题吗？我们将非常感谢您对此问题的任何见解。

我们正在使用Xamarin.Android 4.1.0并且已经在Samsung Note 10.1和Note 3上看到了这个问题。我们还没有在Nexus 7或Sony平板电脑上看到它。

public static void BroadcastResult(string SN, string result, string errorMessage, string commandType = "DataBatch")

    try
    {
         Android.Content.Intent broadcastIntent = new Android.Content.Intent("com.GoServicePro.ProcessorResults");
         broadcastIntent.PutExtra("Type", commandType);
         broadcastIntent.PutExtra("SN", SN.ToString());
         broadcastIntent.PutExtra("RESULT", result);
         broadcastIntent.PutExtra("EXCEPTION", errorMessage);

         if (Global.gCustomizerCol != null)
         {
             if (Global.gCustomizerCol.Count > 0)
             {

             }
         }

         if (Global.CurrentContext == null)
             Android.App.Application.Context.SendBroadcast(broadcastIntent);
         else
             Global.CurrentContext.SendBroadcast(broadcastIntent);

         Logging.LogToProcessorLog("Broadcasted results: <" + commandType + ":" + SN + ":" + result + ":" + errorMessage + ">");
        }
        catch (Exception ex)
        {
            Logging.LogToProcessorLog("EXCEPTION: " + ex.Message + "\n" + ex.StackTrace);
        }
